WINDMILL.

Application filed June 14, 1924. Serial No. 720,037.

To all whom itmay concern:

Be it known that I, FREDERICK RITZ, a citizen of the United States, and a resident of Napoleon, in the county of Henry and State of Ohio, have invented a new and useful Windmill, which invention is fully set forth in the following specification.

V This invention relates particularly to the engines and to the vane control means of windmills, and has primarily for its object to simplify and improve on the arrangement andconstruction of such apparatus whereby to render the same more compact, reduce the number of parts, leisen the cost of manufacture and enhance the efficiency and general practicability and salability thereof.

A further object of the invention is to so construct and arrange the moving parts of the engine with respect to the lubricant in the enclosing'case as to effect an automatic lubrication of the different bearings without the use of additional parts for such purpose.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in different forms,'one embodiment thereof is illustrated the accompanying drawings, in Vwhich,'- Figure 1 is a central, vertical'sectionof anapparatus embodying the invention, with parts broken away, and. Fig. 2 is a crosssection thereof on .the line 2-2 in Fig. 1.

Fig. 3 is a perspective of the connection between the rocker arm and pump rod.

Referring to the drawings, 1 designates a bowl or case having an open top and forming a receptacle orcontainer for a lubricant, the top of the bowl being closed by a removable cap member 1*. Two sets of gears, each of which includes a drive gear 2 and a driven gear 3, the latter of considerably larger diameter thanthe former, are mounted in transversely spaced relation within the bowl 1, and the gears of each set are partially submerged in the lubricant contained in the bowl. The drive gears 22 are mounted on a shaft 4, which extends through the bowl 1, being mounted in bearings 5 on the bowl sides, and having one end projecting beyond the bowl for carrying a wind Wheel, of which the hub 6 is shown.

Each of the gears 3, 3 is carried by the inner end of a respective stub shaft 7 mounted in a bearing 8 in the adjacent bowl side, the shaft, in the present instance, being adapted to turn in its bearing.

The bowl 1 has a hollow or cylindrical neck 9' projecting downward from its bottom between the axes of the gears Qand 3 and mounted for horizontal turning movements on the upper end of a frame or derrick 10. A tubular mast 11 is fitted at its upper end into the neck 9 and projects a distance downward therefrom through an opening in the derrick top for turning movements with the bowl. A set of ball bearings 12 is disposed between the lower end of the neck and an annular bearing plate 13 on the derrick. Angled fingers 14. are secured to the derrick top and engage over a shoulder 15 on the neck'to hold the latter to its bearing onthe plate 13.."

The neck'9 has at its upper endan extension 16, which forms a continuation of'the neck opening and extends up into the interior of the bowl 1 between the two sets of gears therein, adjacent to the points of meshing of the gears of the sets, opening at its upper end into the bowl a point above the lubricant level therein. I i 1 I The usual pump rod- 17 projects up through the mast 11, neck 9 and neck ex-.

tension 16-.into the upper portionof the bowl 1, and has a pair of" links 18 rigidly depending from its upper end. at opposite sides of the rod and neck extension 16 and pivotally connected at'their lower ends to the free forked end 19 of a rocker member 20, the forked end of-i'vhich is disposed in straddling relation to said neck extension.

The pump rod 17 flexes sufliciently to allow I for the arcuate movements of the pivotal connection between the links 18 and rocker 20. The rocker 20 is disposed between the two gears 3, 3, extending transversely thereof, and has its opposite end to that which isieonnected to the pump rod pivotally mounted ona pin or stub shaft 21 that is supported at'its ends in ears 22 projecting inwardly from the'adjacent bowl end. This pivot pin is substantially in a horizontal plane With the axes of the gears 3, 3 so that the rocker member when rocked will cross said axes in a vertical plane. The rocker 20 is provided lengthwise thereof with a slot or elongated opening 23 which receives a roller 24 carried by a pin 25 that extends between the gears 3, 3 and is conr and at each downward rocking movement of the rocker 20 its free end is submerged in the oil, and upon the next upward movement thereof, if of sufficient height, the oil which clings to the rocker will travel down the same by gravity to the roller 241- and pivot pin 21 to lubricate the same. The roller 2 1,,

as it traverses the lower portion of its movement will pick up some oil. and carry it along the rocker toward its pivoted end and a portion of this lubricant will find its way to the bearing pin 21 through a notch or passageway 20 in the rocker. The running of the gears in the lubricant will maintain the bearings therefor properly lubricated, so that the entire mechanism within the case is automatically lubricated by the running of the moving parts.

The manual control for the vane arm comprises the pull member 3]., which tends from a convenient point of access up through the mast 11, neck 9 and neck extension 16 into the upper portion of the bowl 1, thence passes over a guide sheave 32 and outward through a hollow L-shaped arm 33 on the adjacent end of the bowl around a sheave 34 in the outer end portion of said arm, and thence over to its point of connection with the arm 30. The portion of the pull member 30, which extends into the bowl 1 and around the sheaves 32 and 34.- preferably comprises a chain 35. The sheave 34- is horizontally disposed within the arm 38 being mounted on a vertical pin 36 projecting through the arm, and the sheave 32 has its pivot pin 37 mounted at its ends in a pair of bearing arms 38 projecting inward from the adjacent end of the case 1.

It is evident that I have provided a simple and efficient engine construction of the class described, which is composed of few parts compactly arranged within the bowl 1 and is self-lubricating by reason of the operation of the gears and rocker member 20 in the lubricant contained in the case.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts as it is capable of numerous modifications and changes without departing from the spirit of the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a windmill engine, a support, a casing, a de ending hollow neck carried by the casing, a shoulder extending outwardly from the lower end of the neck, and having a depending flange, a ball-bearing plate on the support having the balls thereof enclosed by the flange and the bottom edge of the latter overlying the plate, angled fingers having lower ends seated on the plate and having vertical parts engaged with the and inwardly extending upper ends en aged on top of the shoulder, a tubular mast extending through the support and fitted within the neck and being surrounded by the balls of the ball bearing plate, a pump rod extending through the mast and neck, windwheel operated means within the casing for actuating the pump rod, and bolts extended through the lower ends of the fingers and through the plate to conjointly secure the fingers and the plate to the support.

2. In a windmill engine, a casing, a tubular member in the casing, a windwheel driven shaft projecting into the casing to one side of said member, a pair of spaced drive gears on the shaft, a pair of spaced driven gears journaled in the casing on the opposite side of said member and meshing with the drive gears, a slotted rocker arm in the space between the driven gears pivoted at its outer end within the casing and having a fork on its inner end straddling said tubular member, said rocker arm being disposed approximately in the plane of the axes of rotations of the drive and driven gears, a pump rod extending through the tubular member, a pair of links depending from the upper end of the pump rod and pivoted to said fork of the rocker arm, said links being disposed adjacent to the inner faces of the respective driven gears, and a pin eccentrically carried by the driven gears and extending through the slot of the rocker arm.

In testimony whereof I have hereunto signed my name to this specification.

FREDERICK RITZ.
